A war is brewing and the first battle has already been waged. After rescuing her half brother from supernatural medical testing, Savannah Levine — a young witch of remarkable power and a dangerous pedigree — is battered, but still standing. The Supernatural Liberation Movement took him hostage, and they have a maniacal plan to expose the supernatural world to the unknowing.

Savannah is fighting to save her world as witches, werewolves, necromancers, vampires, half-demons, and all the forces of good and evil — including the genetically modified werewolves known as hell hounds — enter the fray. Uniting Savannah with Adam, Elena, Clay, Paige, Lucas, Jaime, Hope, and other denizens of the Otherworld, Thirteen is a thrilling conclusion to this blockbuster series.

I feel like this was probably the best ending this series could have had.

First of all, at some point in the book, all of the major characters play a part. Nobody’s left out for too long, even including a lot of the more minor players. I loved the focus on magic and the fight to be on the “right side”, and I thought Armstrong did a really great job in designing the lead-up to the final big conflict.

Thirteen is exciting, fun, heartwarming, and heartbreaking, all in one. Some of the things that go on between the characters – for example, Eve, Kristoff, and the Nast higher-ups – almost made my jaw drop completely.

I also liked the way that things were left a bit open at the end. Yes, the “big” problem is resolved, but it’s never implied that everyone lives happily and peacefully ever after. Rather, it’s an ending and a projection for the future that I think is more realistic, and leaves the way open for future adventures. This is something that I’ve had a bit of a problem with when reading fantasy series in the past, and I’m glad that Women of the Otherworld has avoided it.
